I have a very old mac with Mac OS X 10.8 Mountain Lion installed. Unfortunately, upgrade is not an option. I really need to use C++ 20 standart in my QT 5.7.1 for my university projects.
I tried to follow this guide, but it didn't help. Also tried, using the same logic, install new clang. Also didn't work. Can anybody please help? Really need to use modern C++ on this system

C++ version test .pro, C++ version test .cpp, clang installed succesfully
